Wattstopper Delay Switches

Overview

The WATTSTOPPER WSX-PDT-WH is a dual technology wall switch occupancy sensor with integrated relay, designed for indoor commercial and residential lighting control. It combines 100 percent passive infrared (PIR) detection with a secondary sensing technology to deliver reliable occupancy detection and automatic light switching. Rated for 120/277 VAC at 50/60 Hz, it handles loads up to 800 W at 120 VAC or 1200 W at 277 VAC for incandescent and fluorescent fixtures, plus 1/4 HP motor loads. A licensed electrician installs this device as a direct wall switch replacement in standard single-gang boxes. This sensor is suited for small-to-medium indoor spaces such as private offices, conference rooms, break rooms, restrooms, and storage areas. The PIR element covers small motion to 20 feet and large motion to 36 feet, making it effective in rooms where occupants may be relatively stationary. The built-in photocell prevents the lights from energizing when sufficient daylight is already present, reducing unnecessary switching cycles. Time delay is field-adjustable from 30 seconds to 30 minutes without removing the cover plate. Key Features Dual technology sensing: 100 percent digital PIR detection with excellent RF immunity and no interference with other building systems Area coverage: 20 feet for small motion, 36 feet for large motion detection Adjustable time delay from 30 seconds to 30 minutes; pushbutton programmable without cover plate removal Photocell standard — prevents…
